...have depleted their beta cell population considerably. Dr. David Nathan, director of the diabetes center at Massachusetts General Hospital, notes that at this point, there may not be enough beta cells remaining to seed a new population of insulin-growing cells, even with an infusion of stem cells to give them a more hospitable environment. "This study shows that it can work, but how long it will work is a question," he says. Previous studies have shown that after an immune cell transplant, beta cells vigorously produce insulin for about six months, and then start to die off, victims...
Voltarelli's team, however, has managed to show that the stem cells can give long-lasting beta cells a chance to grow - at least ones that can produce insulin for about three years. Other researchers are pursuing intriguing new stem cell options, including stem cells that can be grown from a patient's own skin, which would eliminate the need for extracting immune stem cells from bone marrow. "Every door that we open leads to another door," says Burt. "All research is built by sitting on the shoulders of other studies. This trial is something that will contribute...
With sophomore shortstop Sean O’Hara out with a knee injury, Walsh chose to give the nod to senior Jon Roberts—in left field that is. So while Roberts got the opportunity to field balls off the Green Monster, everyday left fielder Rogers was moved to shortstop...
...cultural shift. Campbell said that doctors can still meet with pharmaceutical representatives—they will just have to buy their own lunch. He also explained that a major financial fallout will be on physician speakers who are paid upwards of $100,000 to $200,000 to give presentations. “Drug companies do not pay the average physician to give a talk for them,” he said. “They pay the superstars.” He added, however, that certain industry relations, such as those involving research funding, are essential for financing the next...
...said Monday. "That's why we haven't been out to talk to you, because we're trying to gather that knowledge and put it in a package and we ask that you do not press us for details on things like that and we're not going to give it because we respect the lives of the other seamen that we're going to try to save...
